How do you change colors?

Looks like a deliberate design decision by your theme’s author(s). There may be an option in your Dashboard to change the colors. Alternatively, use your theme’s built-in custom CSS option, if one exists, or get a custom CSS plugin and use this code:

#rightbar .widgets {
background: #FE6A68;
}

That will make all the widgets the same red color. Or, use this code instead:

#rightbar .widget-first {
background: #eaeaea;
}

That will make all the widgets the same grey color.

In your Child Theme or CSS Editor Plugin try this code:

#rightbar .widgets {
   background: #FE6A68;
}

And this to edit the font color:

#rightbar h2 {
    color: #fff;
}

#rightbar ul li a {
    color: #fff;
}

Thanks guys! The sample image of the theme shows all different colors so I was hoping I could change each tile. Guess not.

You need to add a featured image to each post. The colors will be the background colors of each tile, please check our demo https://demo.vivathemes.com/themes/tiles/
